[0010] With reference to the attached drawings, a multi-knife multi-angle rock breaking device of a rock tunneling machine is composed of a self-reacting frame body 1, a ring-shaped confining pressure loading table 2, a cutter seat 3, a ball hinge seat 4, and a cutter angle adjusting snap ring 5. Z-direction servo actuator 6, rail guide mechanism 7, roadheader cutter 8, rock specimen 9, X-direction servo actuator 10, Y-direction built-in servo actuator 11, horizontal double-layer linear guide 12, three-way pressure The sensor 13 consists of the lateral movement direction of the rock specimen 9 as the X axis, the advancing direction of the rock specimen 9 as the Y axis, and the direction perpendicular to the broken surface of the rock specimen 9 as the Z axis. The X-direction servo actuator 10 is installed between the horizontal double-layer linear guide 12 and the annular confining pressure loading table 2, and the Y-direction built-in servo actuator 11 is installed between the ...
